Development and characterisation of injection moulded, all-polypropylene composites [PDF]

eXPRESS Polymer Letters, 2013
In this work, all-polypropylene composites (all-PP composites) were manufactured by injection moulding. Prior to injection moulding, pre-impregnated pellets were prepared by a three-step process (filament winding, compression moulding and pelletizing). A

Effects of polypropylene fibre on the compressive and splitting tensile strength of concrete [PDF]

Journal of Materials and Engineering Structures, 2018
Concrete is a versatile construction material comprising of cement, aggregates, water and occasionally admixture. It is very good in compression and weak in tension.

Unveiling the flexural strength of corroded prestressed self compacting concrete beams enhanced with M-sand and polypropylene fibres [PDF]

Scientific Reports
Prestressing steel corrosion is one of the barriers to the serviceability of prestressed concrete structures. The presence of aggressive environmental conditions leads to a reduction in the efficiency of the structures by degradation.

Mechanical properties of fibre-reinforced geopolymer-cemented tailings used as backfill. [PDF]

PLoS ONE
Backfill materials are used in underground engineering to fill voids and buried excavated parts. In this study, solid waste was utilised as a raw material mixed with different amounts of polypropylene fibres to determine the optimal sodium hydroxide ...

Influence of Flax Fibre Hybridization on Mechanical Behaviour of Sisal Fibre-Polypropylene Composites Prepared with an Injection Moulding Machine

Advances in Materials Science and Engineering, 2021
Due to their low weight, high specific strength, and low environmental impact, sisal fibre-polypropylene composites have gained popularity. However, the material has a low modulus and poor moisture resistance, among other shortcomings.

Applicability of fractal models for characterising pore structure of hybrid basalt–polypropylene fibre-reinforced concrete

Reviews on Advanced Materials Science, 2023
The pore-structure characteristics of hybrid basalt–polypropylene fibre-reinforced concrete were investigated by using mercury intrusion porosimetry. The applicability of various fractal models in characterising the HBPRC pore structure was compared. The
