Abstract
This paper presents the unique and outstanding properties of hybrid polymer composite (HPC). The various classification of HPC based on the combination of matrices, fibres and fillers in use are brought to bear. The different techniques/methods employed in the production of hybrid polymer composites, ranging from hot press to cold press are being discussed. It is paramount to note that the production process of HPC from start to finish is not without some inherent and external challenges, such as agglomeration of fibre, fillers and weak interfacial adhesion between fillers and matrices. Chemical modification of fibre was identified as one of the ways of proffering solution to this drawback. This study also presents a wide range of the application of HPC as enumerated in this work. The degradation of HPC as a result of natural and accelerated weathering conditions such as ultra violet (UV) rays, heat caused by high temperature, rain and humidity was also discussed. The durability and lifespan of these HPC can be strengthened and prolonged through the use of intumescents and other additives. All of these can help in improving the resistance of HPC to adverse weathering conditions.
